Application filed August 9, 1919. `Serial No. 316,421.

To @ZZ whom it may concern:

Be it known that we, CHARLES J. CALLA- HAN and GEORGE H. ROBERTS,citizens of the United States, and residents of Attleboro, in the countyof Bristol and State of Massachusetts, have invented certain new anduseful Improvements in Separable Buttons, of which the following isaspecification.

This invention relates to .cu' buttons of the class constructed of twomembers detachably connected together, and the object of this inventionis to provide a cuff button of this class having means for positivelylocking the twomembers of the button together and manually operablemeans for disconnecting these two members thus providing a button whoseparts may be readily connected together and which cannot be accidentallypulled apart as is the case with the ordinary separable button. V,

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully de-l scribed, andparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of our improved button.

Fig. 2 is a sectional side elevation through both members of the button,showing the lock-actuating members of the stud.

Fig. 3* is a sectional side elevation showing one member of the buttonand the supporting members of the stud mounted thereon.

Fig. 4- is a perspective view of the stud member in detail, showing thelocking members and also the supporting members of the stud.

Fig. 5- is a top view showing the supporting members of the stud asinclosed within the retaining plate and the operating members asextending through and beyond the periphery of this plate.

Fig. 6- is a view illustrating the blank from which the stud member isformed.

Fig. 7- is a modification illustrating the base end of the socket memberin which square retaining shoulders 13 are illustrated.

Our improved button is constructed of two separate members 10, eachhaving a head 11 and a base portion 12, the shank portions of thesemembers being preferably formed hollow. The socket member of this buttonis constructed at its neck portion 13 to receive and retain the head,the .Stud 14 of the opposite button member. This contracted end ofthesocket member lis preferably provided with a flange 15 of convenientsize to be passed through the button-hole of a cuff' and beretainedtherein even when isconnected from its associate member of the button.

A The stud member of the button is also preferably provided with anout-turned support-4 ing flange 16 on which flange is mounted the stud14.

This stud is ,preferably formed by being first blanked outof sheet stockinto the form illustrated in Fig. 6, having two pairs of arms or members17 and 21 set at right angles to each other. The members 17 uare nextswaged outwardly forming locking lips 18,see Fig. 4, and the ends 19 ofthese members are then turned outwardly and are of a length to extendthrough the binding plate 20 and beyond 'the periphery of the flange 16.The other two members 21 are bent downwardly to form side walls 22 andtheir ends 23 are turned outwardly to rest and be supported upon theflange 16 of the stud member of the button. i

In onder to secure this stud in position on the liange 16 we haveprovided a binding plate 20 with a central opening 24 to fit over thestud 14 and the edge 25 of this plate is rolled over that of the flange16, whereby the out-turned ends 23 of the supporting members are grippedand bound securely to this flange holding the stud in the desiredposition.

At the point where the operating arms 19 pass between this binding plateand the flange the plate is raised a trifle forming a groove throughwhich the operating arms extend and are freely movable.

In constructing this head portion we have formed the members 21 of thestud blank of a width so that when folded they will lie inside thevertical edges of the.locking members 17 as best show n in Fig. 4,thereby serving as a convenient \stop to limit the inward motion of thelocking members when pressed by the thumb and finger of the wearer, toprevent the .permanent setting of the spring which might .be the case ifthese members were pressed 1nwardly too far.

In operating this improved button 1t is only necessary to enter thestudportion 14 in the socket member when with a slight pressure 011 th?@(5,225 Q.f .the QPPOSlte but Patented Nov. 11, 1919.

3. A separable button comprising Atwo releasably -connected members eachhaving a head and a base portion, the base of one member having astud-receiving shouldered socket, an elongated stud portion on the othermember to releasably engage said socket, said stud being formed of a.pair of supporting legswith out-turned ends and a pair of locking legswith out-turned ends longer than those ofthe supporting legs, saidlocking legs being depressible through their out-turned ends andprovided with engaging lips, and means for rigidly securing saidsupportinglegs to their base, said supporting legs being positioned tolimit the releasing stroke ofA said locking legs.

In testimony whereof we affix our signatures.
